WILLIAM L. HARROUN, OF ELLISBURG, NEW YORK.

FLUSH VALVE,

Application filed September To all whom it may concern.

Be it known that 1, Human L. HAR- ROUN, a citizen of the United States, resi ling at Ellisburg, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Flush Valves, of which the following is a specifi' cation.

This invention relates to improvements in flush valves, designed for use in connection with water-closet flush tanks, and has for its object the provision of novel and positive means for seating the flush valves fol lowing each flushing operation. A further object is to provide a novel disc valve, which is supported by and is movable with the usual spherical rubber valve, the said auxiliary valve, during the flushing intervals, being disposed in the path of, and being drawn downwardly into the flush pipe by, the strong suction of the flushing stream, thereby positively and truly seating the flush valve. And a particular object is to improve and simplify the means by which the auxiliary valve is secured to, andby which the flush valve is supported and operated. I"

The present invention. has for its definite object the reduction of the number of parts, as well as the cost, of the valve operating devices shown and described in my United States Patent No. 1,374,655, dated April 12, 1921.

The various features and parts of the invention will be understood from the detailed description which follows, and by reference to the accompanying drawing, in which-- Figure 1 is a vertical longitudinal section through a flush tank, to which my invention is applied. Fig. 2 is an enlarged view, partially in section, of the flush valve and flush pipe; showing the closed and open position of the valve. Figs. 3 and 4 are similar en larged views of the disc valve and the one part operating rod. Fig. 5 is a bottom face view of the disc valve. Fig. 6 is respectively an end and anedge view of the threaded bushin which is embedded in the top of the flush valve. Fig. 7 is a view showing the operating rod in two parts. And Fig. 8 is an enlarged view of the threaded portion of the rod and the bushing.

In the drawing, 2 represents a flush tank,

which receives the flushing water through a pipe 3, theineoming water being controlled by a ball-cock 4 and a float 5. 6 represents,

wards its seat.

the usual i'lush pipe, by which the water is discl'iarged from the tank, the upper end ofted lines in Fig. 2, owing to its natural buoyaney is held away from its'seat 6, until the close of the flushing period, when the suction of the outflowing water draws the valvc'to- In the past, more or less trouble has been esperieiwed with the proper seating of flush valvesof the class, due to the tendency of said valves, when approaching their seats, to gyrate with the eddying and swirling flushing streams. This frequently causes the flush valve to impinge against one side or the other of the seat, and to become canted to such extent that the flushing is either prolonged, or else the discharge continues like a leak until the valve is restored to its proper position. To overcome this trouble, 1 provide a valve comprising a disc, as 14, which is normally positioned in the flush pipe 6, preferably in line axially with said pipe and the valve 7.. The diameter of the disc 14 is smaller than the bore of the pipe 6, and when the valve 7 is lifted, as shown by dotted lines in Fig. 2, the

disc is positioned slightly above the seat 6, directly in the path of the gravitating waten. As the water in the tank recedes, the ball 7 and the disc 1 1 gradually descend, and the last of the flushing stream draws the disc downwardly until it effects the positive seating of the ball. The subsequent refilling of the tank tends to hold the valves 7--.14 in the closed position, shown by full lines in Figs. 1 and 2.

In the present case, the valve 7 is provided with top and bottom axial openings 7-7, for the insertion of the one-part operating rod 13. For this purpose the top. opening 7 is provided with an internally threaded metal bushing 15, which is preferably permanently embedded in the material of the valve when the latter is molded. The rod is preferably inserted downwardly through the valve 7, and in order to suitably secure the rod and valve together, the medial portion of the rod is flattened, as at 13, by means of suitable swaging dies, and the laterally bulging portions resulting from the displacement of the metal are threaded for screwing into the bushing 15, as shown in Figs. 2 and S, in which the bushing is shown threaded downwardly to a point near the bottom of the opening,'aml below the threaded portion the opening of the bushing is preferably plain and snbstnmtiahy the same diameter as the nnllattened portion ot the rod, for preventing leakage through the said opening into the valve 7. The lower end of the rod 13 is also threaded and screws into a central threaded opening of the disc 14. The top end of the rod 12-3 is preferably formed with a loop 123*, which is shown .engaged by the hook-endot' the operating rod 12. Between the valve 7 and the rod 12-, the rod 13 passes loosely through a guide 16, which is supported by the usual overflow pipe 17 common to tanks of the class.

The rod 13 takes the place of the rods 8 and to and the collar 10',.ot my former patent, and the bushing 15 replaces the former sleeve,1'1. This change in the construction and arrangement of the operating parts has been rendered necessary, in order to reduce the cost of making and assembling the parts, and particularly for the reason that the continual jars and vibrations resulting from the more or less jerky and rough handling of the flushing mechanism by the users of the closet, tends to loosen the former complicated operating parts, and seriously intertires with the proper and effective operation oi the flushing mechanism.

To apply my improved flushingmcchanism to a tank of the class shown, the plumber takes the.r0d 13 and inserts its threaded end downwardly through the guide 16, the lower end of the rod is next passed downwardly through the valve 7, and the threat-led portion 13 is screwed into the threaded socket ot' the bushing 15 until it comes to a stop, as shown in Figs. 2 and b. The connected rod and valve are then lifted upwardly, as from the full line to the dotted line position shown in Fig. .2, for applying the disc 14; to the threaded lower end of the may be applied to the old style of flushing mechanisms, either with or without the valve 14.

Having thus described my invention, what I claim, is-

1. The COIIlbll'lzlliOll with a. flush valve and a disc disposed below said valve, of a thread-- ed bushing embedded in the top of said valve, and a rod passing axially through said valve and disc, the n'icdial portion of said rod being flattened for providing laterally projecting portions which are threaded "for screwing into said bushing, and means for detachably securing the disc to the rod.

2. The combination with a flush valve having a threaded bushing en'ibet lded in its top end, a flush pipe, and a disc-shaped valve spaced below the flush valve, of a rod inserted downwardly through the flush valve and supporting said disc valve concentrically in said pipe, said rod having'its medial portion flattened and the bulging lateral sides thereof being threaded for screwing into the bushing.

In testimony whereof I atfix my signature.
